Main Question or Discussion Point

i have this example of a hydrostatic force on a plane surface.

what i dont understand is how the width of the integral strip is derived

it says w(s)=b(s-s1)/L i dont understand how this comes about?

would be really greatful if anyone could direct me i cant find anything on triangular lamina double integration :S

cheers!

just draw a perpendicular from the vertex on the base and then use the property of similar triangles.
w/b=S-s1/L
